Hello Ettiene, There is now a much simpler and less buggy way of using bgIframe. It is described on the updated Superfish documentation page, here: http://users.tpg.com.au/j_birch/plugins/superfish/#sample2
You will need to make sure you are using the most up-to-date version of bgIframe which you can get here: http://brandonaaron.net/jquery/plugins/bgiframe/docs/#where_can_i_get_it The improved code for applying bgIframe to Superfish is this: $(document).ready(function(){ $("ul.sf-menu").superfish().find('ul').bgIframe({opacity:false}); }); Much simpler than the older method that you are currently using.
